CAN STOPPER.

SPECIFIGATION forming part of Letters Patent No. 413,546, dated October22, 1889. Application filed July 11,1889. Serial marines. (No man.)

T on whom it may concern.-

Be it known that I, HENRY PEARL, a citizen of the United States,residing at Mount Vernon, Westchester county, State of New York, haveinvented a certain new and use ful Improvement in Oan-Stoppers, of whichthe following is a specification.

My invention relates to automatic canstoppers for volatile or otherliquids, and has for its object the provision of a device simple inconstruction, cheap in manufacture, and efficient in practical use.

To attain the desired end my invention consists in the construction andarrangement r 5 of parts hereinafter described,and pointed out in theclaim.

In the drawings which form a part of this specification, Figure 1represents a perspective view of a can provided with my automatic 2ostopper. Fig. 2 is a side elevation of the stopperin an open position.Fig. 3 is a top view of the same; and Figs. 4, 5, and 6 are sectionalviews, respectively on the lines y y, Fig. 3, :c at, Fig. 4, and x 00,Fig. 5.

Similar letters refer to similar parts wherever they occur on thedifferent parts of the drawings.

-A is a can or liquidreceptacle made of metal or other suitablematerial. To its up- 0 per end is soldered or otherwise secured in anair-tight manner the nozzle B, preferably provided with an annular ring1), adapted to form a flaring mouth for the same. The nozzle B isprovided with an outwardly and up- 3 5 wardly projecting arm 0, whichserves to support an integral rigid barrel D and an independentconcentric movable barrel D', the barrel D being provided with a neck 01andshoulder cl, and the barrel D with an annular flange d for thepurpose of a'lfording a frictional connection between the barrels, so

that the barrel D may be turned to any desired position by manipulatingthe thumbpiece D ,with which it is provided. The movable barrel D isalso provided with an extension or disk D which normally covers thenozzle B and forms the stopper proper, and which has a preferablyinverted-cone-shaped cushion, of rubber or other elastic material,

5o thereunder placed, the parts being suitably secured together, as bythe washer e and rivet e. The barrels D D are held together in a movablerelation by the axial rod F, provided at one end with a head f and atthe other extremity with a pin or spring cotter f, as is clearly shownin the drawings.

Placed within the barrels D D, and coiled around the axial rod F, is thespiral spring G, the respective hook ends 9 g of which are engaged withthe barrels D D, in the present '60 instance the hook g resting inagroove d formed in the interior side wall of the barrel D, and the hook.9 being held in the recess 01 in the opposite interior side wall of thebarrel D.

In practical operation, the cushion E is normally held against andengages with the mouth of the nozzle B when the stopper is closed bymeans of the resiliency of the spring G', thereby serving as a cork, andthe elastic properties of the same adapt it to projectinto and conformto the shape of the mouth and to form an air-tight seal therefor.

By my device the can is at all times sealed,

exceptwhen manipulated for the purpose of 7 5' filling or emptying, andthe stopper will close automatically as soon as the pressure on thethumb-piece D is removed.

The operating parts are protected, and are thus not liable to becomebroken or deranged through accident or usage, and if by any means thecan should be overturned during transportation or while in use anyleakage of the same will be prevented.

hat I claim as new, and desire to secure" by Letters Patent, is

In a can-stopper, the combination,with the nozzle B, provided with thearm 0, carrying the barrel D, of the spring-actuated barrel D, journaledon the barrel D and provided with 0 the stopper D and theactuating-spring carried by said barrels, substantially as described.

In testimony of the foregoing specification I do hereby sign the same inthe city, county, 9 5' and State of New York, this 21st dayof June A. D,1889. I

HENRY PEARL.
